Ukrainian defense startup Falcons has secured funding from US-based Green Flag Ventures to enhance its electronic warfare system, particularly its ETER radio frequency direction-finding device, which has already proven effective in combat against Russian systems. This investment aims to scale production and develop a NATO market-entry strategy, highlighting a growing trend of Western interest in agile and cost-effective defense solutions amid ongoing warfare. The ETER system, designed for GPS-denied environments, offers a significant financial advantage over traditional NATO systems, underscoring the potential of rapid technological advancements in defense during crises like the one in Ukraine.
